2. ) Procedures, contents of the waste water statistics in Germany Structure of waste water management and statistics Disposal of waste water generated by the domestic and the industrial sector through urban waste water collection systems and treatment plants Statistic on public water supp and urban waste water disposal (§ 6 UStat. G) run by municipalities or companys (governmental or private) Statistic on water use and waste water disposal by mining, quarrying, manufacturing industry (§ 7 UStat. G) and by production of electricity (§ 9 UStat. G) © Federal Statistical Office of Germany, Birgit Hein, Head of division for environmental statistics Folie 9 Discharge and treatment of waste water by the industrial sector Wien, 21. 06. 2005

Joint Questionnaire) Table 4: National population connected to waste water treatment plants + everything is available up to one position - not available: independent waste water collecting system including secondary treatment Table 5: Treatment capacity, in terms of BOD for the different types of treatment Table 6: Sewage sludge production and disposal (volume and tons of dry solids) for the different types of treatment © Federal Statistical Office of Germany, Birgit Hein, Head of division for environmental statistics Folie 12 Wien, 21. 06. 2005

3. ) International Reporting on waste water (e. g. Joint Questionnaire) Table 7: Part I - Volume Waste water generation by point sources (different sectors) and non point sources + data are available for most of the industrial sectors - no data from agricultural sector or construction sector - no data for non point sources Waste water discharged by type of collecting system + most of the data are available - no delivery of data on waste water reused and for the detailed positions of waste water generated by the domestic sector Table 7: Part II - BOD, COD, - data are only available on effluents of urban Suspended Solids, N-Tot, P-Tot, As, treatment plants for COD, N-Tot und P-Tot Population Equivalents, selected hazardous substances for the same classification than in part © Federal Statistical Office of Germany, Birgit Hein, Head of division for environmental statistics Folie 13 Wien, 21. 06. 2005

4. Problems to fulfill the requirements General reasons: • • • For collecting new data a modification of the law is necessary • „ Länder“ also collect data, this results in double surveys parallel to the statistics The long tradition hinders modification Actually the politics plan to reduce the „statistical burden“ for enterprises - Water politics are primarily in their hand - The European Commission requires data, e. g. Urban Waste Water Directive“ • Other additonal data collection: Environmental agency; EPER • • • Data collection is conducted only every three years Some sectors are not included (services, contstruction, agriculture) Overlapping parts are difficult to report while the statistics are subdivided in two parts © Federal Statistical Office of Germany, Birgit Hein, Head of division for environmental statistics Folie 14 Wien, 21. 06. 2005

4. Problems to fulfill the requirements Specific reasons • • Degree of detailing is particular very high, but the political need is not clear the tables are often organized from a more theoretical point of view Deviation of definitions Conclusion • • • Concentration of the priority data Extension of the use of other databases (UGR, EPER) Improvement of coordination between the different requirements (primarily within the EU) © Federal Statistical Office of Germany, Birgit Hein, Head of division for environmental statistics Folie 16 Wien, 21. 06. 2005
